Large Output Vertical Grinding Mill Machine For Barite And
【Application Field Of Bentonite Powder】
Due to its good physical and chemical properties, bentonite can be
used as a decolorizing agent, binder, thixotropic agent, suspending
agent, stabilizer, filler, feed, catalyst, etc. It is widely used
in agriculture, light industry, cosmetics, pharmaceuticals and
other fields. It is also used as waterproof material, drilling mud
bentonite, so montmorillonite is a natural mineral material with a
wide range of uses.
Bentonite powder milling process
Due to the relatively large water content of bentonite, the raw
material needs to be dried to a moisture content of less than 6%.
After drying, the lumpy bentonite is transported to the raw
material warehouse by a special vehicle.
The dried bentonite is lifted to the storage hopper by the
elevator, and the storage hopper is discharged and then fed to the
host by the feeder evenly.
In the grinding process, the qualified products are screened by the
screening system and then enter the collector through the pipeline.
After being collected, they are discharged through the powder
discharge pipe to be the finished product. The unqualified products
fall into the main engine for re-grinding.
The purified air flows through the residual air duct above the dust
collector and flows into the blower. The air path is circulating.
Except for the positive pressure from the blower to the grinding
chamber, the airflow in the rest of the pipeline flows under
negative pressure, and the indoor sanitary conditions are better.
Bentonite pulverizing equipment is used in large-scale non-metallic
ore pulverizing, environmentally friendly desulfurization limestone
pulverizing, calcium carbonate pulverizing, large-scale pulverized
coal equipment, petroleum coke fuel industry, manganese ore
processing, comprehensive utilization of slag, water slag, fly ash,
gypsum milling and many other fields.

Re:The data based on Mohs'hardness 3-4 material
The product fineness can reach 10 um(1250 meshes)
1. The superfine vertical mill adopts the principle of high-efficiency and energy-saving material layer grinding, with high grinding
efficiency and low energy consumption; the single machine has a
large production capacity and can utilize low-valley electricity;
the vertical grinding technology and equipment are new
energy-saving and consumption-reducing technologies vigorously
advocated by the state. , which is conducive to enhancing the
competitiveness of enterprises in the powder industry in this
region and even the whole country;
2. Strong applicability and low investment Adopt secondary classification to realize
multi-purpose of one machine, strong practicability of equipment,
and save investment cost.
3. The product quality of calcite ultrafine vertical mill is stable
(1) The material stays in the pulverizer for a short time, and it
is easy to detect the particle size distribution and composition of
the product, and the product quality is stable;
(2) The product has uniform particle shape, narrow particle size
distribution, good fluidity and strong product adaptability;
4. Easy maintenance and low operating cost
(1) The grinding roller can be turned out of the machine by
hydraulic device, the replacement of the roller sleeve lining plate
and the maintenance space of the grinding machine are large, and
the maintenance operation is very convenient;
(2) The roller sleeve can be turned over for use, which prolongs
the service life of the wear-resistant material;
5. Environmental protection
(1) The whole system of HLM vertical mill has small vibration and
(2) The system is sealed as a whole, operates under full negative
pressure, and has no dust spillage, which can basically realize a
6. Low wear, grinding rollers and disc linings are made of special materials and have a long service life;
7. The calcite ultrafine vertical mill has a high degree of automation: the automatic control technology adopts the German Siemens series
PLC, equipped with an automatic control system, which can realize
remote control and easy operation. The workshop can basically
realize unmanned operation and save operating costs.
8. There is no need to put cloth on the grinding disc before starting the calcite ultra-fine vertical mill, and the
mill can be started with no load, eliminating the trouble of
